As authorities intensify their search for the individual suspected of a shooting spree at Brown University, resulting in the tragic deaths of at least two individuals and injuring nine others, a seasoned law enforcement expert underscores the often chaotic nature of early reports. The expert advises that police must meticulously validate information before proceeding.

“In incidents like this, initial details can frequently shift and sometimes do so quickly,” noted Jason Pack, a retired FBI Supervisory Special Agent with 21 years of experience. “The early information typically comes from various stressed sources, and it’s crucial for law enforcement to confirm each piece before taking action or making it public.”

Pack further explained, “Officers are currently engaged in one of the most challenging aspects of policing, which involves methodically clearing buildings that are under lockdown.”

He emphasized that the work being carried out by law enforcement is “a slow, deliberate, and hazardous task.”

“Every hallway, every stairwell, every classroom and office has to be treated as a potential threat until it’s cleared,” he said.

An unidentified male gunman was last seen leaving the Barus and Holley engineering building at the prestigious Rhode Island university after the shooting at about 4 p.m. local time.

Multiple local law enforcement agencies, along with the FBI and U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) are investigating. Officials have said the alleged shooter was dressed in black.

Pack said that officers at the scene are “moving methodically, often in low light, with limited information, and with the understanding that someone inside those buildings may be frightened, hiding, or unable to communicate clearly.”

“That requires discipline and restraint, not speed,” he said, adding that the search may extend into Sunday. “This is why timelines stretch and why you may hear updates that evolve over the night. Law enforcement is balancing two responsibilities at once: moving fast enough to protect lives, but slow enough to make sure nothing is missed.”

Pack said law enforcement’s goal is “simple but not easy.”

“Make sure every space is safe, every person is accounted for, and that the threat is fully resolved before restrictions are lifted,” he said.
